High intrinsic flux pinning strength of BaFe2-xCoxAs2 superconductor
K. Vinod, Shilpam Sharma, A. T. Satya +2
The field dependence of flux pinning potential, U0, for under-doped, optimally doped and over-doped Ba(Fe,Co)2As2 single crystals has been investigated. U0 is determined using the…
Superconducting and critical properties of PrOFe0.9Co0.1As: effect of P doping
Shilpam Sharma, Jai Prakash, Gohil S. Thakur +4
PrOFe0.9Co0.1As is known to be a superconductor with a TC of ~14 K. In an attempt to induce charge transfer and also induce chemical pressure between the FeAs and PrO layers we hav…
Upper critical field anisotropy in BaFe2-xCoxAs2 single crystals synthesized without flux
K. Vinod, A. T. Satya, Shilpam Sharma +2
The upper critical field was measured upto 12 T for three BaFe2-xCoxAs2 single crystals with estimated Co concentrations of x = 0.082, x = 0.117 and x = 0.143. HC2 versus temperatu…
Superconducting Fe(1+delta)Se(1-x)Te(x) thin films: Growth, characterization and properties
T. Geetha Kumary, Dipak Kumar Baisnab, J. Janaki +5
Thin films of Fe(1+delta)Se(1-x)Te(x) (delta ~ 0.18 & x ~ 0.5) have been successfully grown on (100) oriented single crystalline SrTiO3 and LaAlO3 substrates by pulsed laser deposi…
Critical properties of superconducting Ba1-xKxFe2As2
A. Bharathi, Shilpam Sharma, R. Paulraj +3
Magnetisation and magnetoresistance measurements have been carried out on superconducting Ba1-xKxFe2As2 samples with x=0.40 and 0.50. From low field magnetization data carried out…
Superconductivity in Ru substituted BaFe2-xRuxAs2
Shilpam Sharma, A. Bharathi, Sharat Chandra +6
The occurrence of bulk superconductivity at ~22 K is reported in polycrystalline samples of BaFe2-xRuxAs2 for nominal Ru content in the range of x=0.75 to 1.125. A systematic suppr…
